<p>Once the configuration model is defined and the CMS configured accordingly, control can be exercised over all updates to the CI records in the CMS, for example by specifying who is authorized to make particular types of changes in the CMS and by reviewing updates to the CMS.</p>

<p>The information in the CMS is also subjected to regular audits in order to ensure that it is an exact representation of the configuration items in the live productive environment.</p>

<p>Configuration information is an important input for virtually every YaSM process. For example, it is essential for the resolution of incidents and problems to know precisely what types and versions of infrastructure items are installed.</p>
<p>&nbsp;</p>

<p><i><u>Compatibility</u>: The YaSM configuration management process is <a href="/wiki/en/index.php/YaSM_and_ISO_20000#ISO_20000_requirements_and_related_service_management_processes" title="YaSM and ISO 20000">aligned with ISO 20000</a>, the international standard for service management (see ISO/IEC 20000-1:2018, <a href="/wiki/en/index.php/YaSM_and_ISO_20000#Service-portfolio" title="ISO 20000 section 8.2: Service portfolio">section 8.2</a>), and it corresponds to the practices of '<a href="/wiki/en/index.php/YaSM_and_ITIL#ITIL-4-Service-configuration-management" title="ITIL 4 practices and YaSM processes: ITIL 4 service configuration management">ITIL 4 service configuration management</a>' and '<a href="/wiki/en/index.php/YaSM_and_ITIL#ITIL-4-IT-asset-management" title="ITIL 4 practices and related YaSM processes: IT asset management">IT asset management</a>'.</i></html>

==Sub-processes==

<html>YaSM configuration management has the following sub-processes:</p>

<dt itemprop="name">Change record</dt>
<dd itemprop="description" style="margin-bottom: 1em;">A change record contains all details of a change, documenting the lifecycle of a single change. In its initial state, a change record describes a request for change (RFC) which is to be assessed and authorized prior to implementing the change. Further information is added as the change progresses through its lifecycle. <a href="#ydo" title="YaSM data object">[*]</a></dd></div>

In this context, CIs can be of various types: Applications, systems and other infrastructure components are treated as CIs, but often also services, policies, project documentation, employees, suppliers, etc. Configuration information is stored in the configuration management system (CMS). <a href="#ydo" title="YaSM data object">[*]</a></dd></div>

<p><i><u>Notes</u>:</i>
</p><p><span id="ydo"><strong>[*]</strong> <i>"YaSM data objects"</i> are those documents or records for which the YaSM model provides detailed recommendations: Every YaSM object has an associated checklist (see <a href="https://yasm.com/wiki/en/index.php/Service_Management_Checklists" title="Example: YaSM service management checklists and document templates">example</a>) describing its typical contents, and an associated lifecycle diagram depicting how the status of the object changes as it is created, updated, read and archived by various YaSM processes (see <a href="https://yasm.com/wiki/en/img/yasm-project/Yasm-object-lifecycle-diagram.jpg" title="Example: YaSM object lifecycle diagram (.JPG)">example</a>).</span>
</p><p><i>"Other objects"</i> are mostly informal data or information where YaSM has less strong views about their contents. There are no associated lifecycle diagrams or checklists.</html>

==Process metrics==

Process metrics are used, for example, to assess if the service management processes are running according to expectations.

For suggestions of [[Service Management Metrics|suitable metrics]], please refer to the [[Service_Management_Metrics#Metrics_for_the_configuration_management_process|list of metrics for the YaSM configuration management process]].

==Roles and responsibilities==

<span id="responsible">Process owner: The '''configuration manager''' is responsible for maintaining information about the infrastructure required to deliver the services. To this end he/ she maintains a logical model describing the components of the infrastructure and their associations.</span>
